Abstract/Contents:"Plant tissue analyses indicate the chlorotic trees are below the critical range for foliar concentrations of phosphorous and manganese. Soil analysis indicates that extractable levels are present. This does not mean the plant can utilize those elements present and indications are they are not doing so. High soil pH around the pines probably resulting from the liming potenital of the irrigation water may be causing formation of insoluble Ca-P, Ca-Mn-P, Ca-Fe-P, or Ca-Fe-Mn-p compounds thus making manganese and phosphorous unavailable physiologically. Additional studies are necessary to determine if this high soil pH may be interfering with mycorrhizal infection and phosphorous uptake. A recommended soil pH range for pines is 3.8-4.5 which provides ideal growth and nutrient availability. Lime added from the irrigation water has raised the soil pH far above this range and this probably accounts for a major portion of the problem."
